4.3 Intercepts
The ________________________ is the point where a graph crosses the ____________.
The y-intercept is ________________________________________________________.
FINDING INTERCEPTS
• To find the x-intercept of a graph, plug in __________________ and solve for x.
• To find the y-intercept of a graph, plug in __________________ and solve for y.
Ex1:
• Find the x-intercept and y-
intercept of 2x + 3y = 6.
x-intercept: y-intercept:
• Graph the equation.
Ex2:
• Find the x-intercept and y-
intercept of x – 2 = 4y
• Graph the equation.
